Here you go Kevin, some colour pics of Mk1's from 2 Sqn at Sawbridgeworth, taken on the Press day in July 1942. The first three show XV-U, AG550, which was lost when it hit a hill, at Kimmeridge, Dorset, in fog on 26 May 1943, killing the pilot.
The second two, obviously the same shot, but one with better satuaration, show XV-E, AG633 over Essex. This aircraft also crashed, overshooting on landing on 29 October 1942, at Sawbridgeworth.
Detail points to note:- the leading edge yellow I.D. stripes extend from wing tip to the the root fillet. Individual code letter repeated under the nose, and natural metal, early style pilot's seat.
Hope these are useful.
